well it didn't give me the junior option....its not a little girls dress....for sure....I would say it would fit a girl size 10-12 or a small junior......I hope that helps.....
I going to add another pic tonight holding it up against me so people can have a better idea......I got two and the other one fit my daughter and she was 14 size 3 so really it just depends.......
I looked again and it says a small junior.....what size cloths does the one your wanting this for were....it also has an elastic waist band so it can be a little flexible regarding size....if your junior is petite and short....this would be perfect....I hope this helps a little.....
